Canon has announced updates to two of their lenses—the EF 16-35mm f/2.8L III USM and EF 24-105mm f/4L IS II USM.

Canon EF 16-35mm f/2.8L III USM

This update of the 16-35mm f/2.8L features better durability and water resistance, and now has a large-diameter GMO dual-surface aspherical lens and a ground aspherical lens which supposedly fixes the Mark II’s edge-to-edge performance.

The lens will be available from late October at US$2,200.

The new incarnation of the 24-105mm f/4 now features 4-stops of OIS (1 more stop from the previous version) according to Canon. The optical performance is improved as well, with the help of “air sphere coating”.

The lens will be available from late October for US$1,100.

W-E1 SD Card-Shaped WiFi Adapter

Canon says this was specifically created to bring WiFi capability to the Canon EOS 7D Mark II, though it’s also compatible with the 5DS and 5DS R. It’s supposed to be sold with the 7D Mark II to give it the same level of camera control and transfer capabilities as the newly released 5D Mark IV.

Unlike the SD WiFi cards like the Toshiba FlashAir and EyeFi, the W-E1 does not have any storage. As such, you would have to use the CF card slot for your images and/or videos. Used with the 7D Mark II, you can transfer both images and videos, but on the 5DS/5DS R, you can only transfer images.
